For industrial buyers, chemical procurers, and supply chain managers, bulk n-propanol (1-propanol, CAS 71-23-8) procurement requires precise grading, packaging matching, supplier verification, and export compliance. Unlike small-batch laboratory purchases, bulk trading focuses on consistent purity stability, batch-to-batch uniformity, cost efficiency, and global shipping feasibility. This guide is tailored for B2B bulk purchasers, covering core selection standards, full packaging solutions, MOQ rules, lead time arrangements, essential export documents, and professional supplier evaluation checklists to help you complete stable and cost-effective bulk procurement.

What Is Bulk N-Propanol for Industrial Procurement?

Bulk n-propanol refers to large-volume commercial-grade 1-propanol supplied for industrial continuous production, commercial formulation, and large-scale chemical processing, rather than lab reagent packaging. It is a colorless, clear, and volatile primary alcohol with stable physical and chemical properties, widely used in coatings, inks, industrial cleaning, pharmaceutical intermediate synthesis, pesticide production, and cosmetic solvent preparation .

In bulk trade scenarios, n-propanol is strictly differentiated from isopropanol (2-propanol) to avoid application failures. Bulk-grade products feature standardized impurity control, fixed batch production, and complete quality traceability, which are core indicators that distinguish industrial bulk goods from scattered retail reagents. All bulk shipments comply with international chemical transportation standards and industrial production access requirements.

Common N-Propanol Bulk Specifications & Technical Indicators

Bulk n-propanol procurement relies on standardized technical indicators to unify quality standards across suppliers. The mainstream bulk technical parameters adopted by global industrial supply chains are as follows, covering core indicators for production quality control:

• CAS Number: 71-23-8
• Molecular Formula: C₃H₈O
• Molecular Weight: 60.10 g/mol
• Appearance: Clear, colorless transparent liquid, no suspended impurities or precipitation
• Odor: Typical mild alcohol odor, no peculiar pungent smell
• Density (20°C): 0.803 g/cm³
• Boiling Point: 97°C
• Flash Point: 15°C (strict flammable liquid transportation control required)
• Refractive Index: 1.384 (20°C)

Batch core quality control indicators include purity, water content, acidity, and non-volatile residues, which directly determine the applicability of n-propanol in different industrial scenarios .

Industrial Grade vs High-Purity Grade: Core Grade Differentiation

The core of bulk n-propanol procurement is grade selection. Industrial grade and high-purity (reagent/ACS grade) have clear differences in impurity control, application scope, and pricing, which are the key basis for purchase matching .

1. Industrial Grade N-Propanol

Industrial grade is the mainstream bulk trading grade, with a purity of ≥99.0%. It adopts industrial continuous distillation production, meeting the large-scale use needs of most basic industrial scenarios. The water content is controlled within ≤0.5%, and non-volatile residue is ≤10 ppm. It features high cost performance, sufficient global supply, and flexible batch delivery .

Main Applications: Coatings and ink solvents, industrial metal cleaning agents, paint diluents, general chemical synthesis intermediates, and daily chemical raw material solvents.

2. High-Purity (ACS/Reagent) Grade N-Propanol

High-purity grade is a refined upgraded product with a purity of ≥99.5%. After secondary rectification and impurity removal, the water content is strictly controlled ≤0.2%, non-volatile residue ≤5 ppm, with extremely low heavy metal and organic impurity content, meeting ACS analytical reagent standards .

Main Applications: Pharmaceutical intermediate synthesis, laboratory analytical testing, high-precision electronic cleaning, cosmetic high-grade solvent preparation, and fine chemical production with strict impurity requirements.

How to Select the Right N-Propanol Purity for Your Production

Improper grade selection will lead to production quality instability or excessive procurement costs. Buyers can select purity standards based on production scenarios and process thresholds:

• Choose Industrial Grade (≥99.0%): Suitable for mass production of coatings, inks, industrial cleaning, and basic chemical synthesis. The process has low sensitivity to trace impurities, and industrial grade can fully meet production standards while optimizing procurement costs.
• Choose High-Purity Grade (≥99.5%): Mandatory for pharmaceutical synthesis, fine chemical processing, electronic grade cleaning, and laboratory precision analysis. Trace water and residues in industrial grade will cause product purity failure and reaction deviation, so high-purity grade must be adopted .
• Customized Special Grades: For anhydrous production processes, suppliers can provide customized low-water-content products (water content ≤0.1%) to meet special process requirements .
