Introduction
Analysis of the Standard Core Framework
| Classification Dimensions | Hierarchical Structure | Coding Rules | Typical Applications |
|---|---|---|---|
| Major Categories (10 Categories) | Classification by Purpose | 1 Latin Letter (AQ) | Industry Statistics, Warehousing Planning |
| Middle Categories | Structure/Use Segmentation | 2 Digits (01-99) | R&D Direction Positioning |
| Minor Categories | Specific Compound Types | 2 digits (00-99) | Experimental design |
Key technical features
Coding system example:
B0302 means:
B (basic organic chemical reagents) → 03 (alcohols) → 02 (monohydric alcohols containing substituents) → such as 2-chloroethanol
Special classification instructions:
- High purity reagents: purity grade marking (3N-5N)
- Standard substances: exclude biochemistry
- Life science reagents: include biological standards
Implementation suggestions
Construction of laboratory management system:
- Establish an electronic ledger based on five-digit coding
- Hazardous reagents are marked with corresponding medium-class codes (such as potassium cyanide is classified as A05)
- Separate files for isotope reagents (Class H)
Optimization of procurement management:
| Scenario | Classification application |
|---|---|
| Teaching experiment | Give priority to I08 teaching-specific reagents |
| HPLC analysis | Select F05 eluent + F06 stationary phase combination |
Standard evolution analysis
Compared with the traditional classification method by purity, this standard innovatively adopts a two-dimensional system of purpose + structure:
- 2008 version: only distinguishes between analytical purity and chemical purity
- 2019 version: newly added classifications for modern scientific research needs such as instrumental analysis reagents (Class F) and life science reagents (Class G)
- The first establishment of an isotope reagent (Class H) management system
