ACS Reagent Grade
Chemical Supplier

ACS Reagent Grade chemicals meet the purity, identity, and quality specifications published by the American Chemical Society Committee on Analytical Reagents. ACS specifications cover:

• Assay (purity) — a minimum set per chemical (for example ≥99.5% for isopropyl alcohol, 36.5–38.0% for hydrochloric acid)
• Identity verification — IR spectroscopy, melting point, etc.
• Limit tests — heavy metals, sulfated ash, residual solvents, water content
• Specific impurity controls — chemical-specific contaminants below threshold

ACS Reagent grade is the working standard for research laboratories, analytical chemistry, R&D, and any application requiring quantitative purity guarantees.

• Technical Grade — industrial process, cleaning, low-purity applications
• ACS Reagent Grade — analytical chemistry, research labs, R&D, quantitative work
• ACS Plus / ACS Reagent Plus — meets ACS spec with additional purity criteria (low metals, low water, etc.)
• USP Grade — pharmaceutical, cosmetic, food, supplement manufacturing
• HPLC Grade — high-performance liquid chromatography

ACS Reagent is the default choice for research-grade work. Step up to ACS Plus when trace contamination matters. Switch to USP when FDA-regulated finished products are involved.

1. Request the Certificate of Analysis (COA) referencing ACS specifications
2. Confirm the lot meets each ACS limit test (assay, water content, heavy metals, etc.)
3. Match the COA lot ID to the container labeling
4. Verify the manufacturer is recognized for ACS-grade production
5. Store the COA with your lab notebook or QMS records for audit trail

The lot-specific COA is available on request at no charge. Lot traceability matches container labels.
