A look-up table of the 50 DUKSAN Pure Chemicals items available at QEMIX: product name, DUKSAN Product No., CAS number, grade, assay and pack size — grouped by chemical class for quick selection when preparing an order.
The Product No., grade and pack size in the table were checked against DUKSAN’s online catalogue (duksan.kr) in September 2026. Click a product name to open its page, see stock status and request a quotation; items not listed here can be ordered from the factory by QEMIX.
Four columns to check before ordering
Product No.
DUKSAN’s product code, tied to one combination of name + grade + pack size. This is the code to put on quotation requests and purchase orders; QEMIX uses it as the SKU on the website.
CAS number
Identifies the chemical substance. One CAS number can have several Product Nos. — for example Sulfuric Acid 95% has separate codes for the 1 L and 2.5 L packs.
Grade
In the table: GR = Guaranteed Reagent (analytical grade), EP = Extra Pure (general-purpose grade), HPLC = chromatography-grade solvent, GR/AR/ACS = analytical grade that also meets the standards stated on the label. How to choose a grade for your test: see the DUKSAN introduction.
Assay and pack size
Assay according to DUKSAN’s Specification; the actual value for each lot is on the COA. Pack size is the smallest packaging unit for that code.
