IUPAC name: benzenesulfonate;5-[3-[(1R,2R)-1-[(3,4-dimethoxyphenyl)methyl]-6,7-dimethoxy-2-methyl-3,4-dihydro-1H-isoquinolin-2-ium-2-yl]propanoyloxy]pentyl 3-[(1R,2R)-1-[(3,4-dimethoxyphenyl)methyl]-6,7-dimethoxy-2-methyl-3,4-dihydro-1H-isoquinolin-2-ium-2-yl]propanoate
Method for the $250 identity, purity and quantity test: HPLC-UV purity and assay, LC-MS identity, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by infrared spectroscopy and HPLC retention time, assay by HPLC, organic impurities and methyl benzenesulfonate by HPLC, and optical rotation, water and residue on ignition. Full testing to the USP Cisatracurium Besylate monograph is available and quoted.
Chromatographic purity and mg per unit by the method matched to the compound, identity against a reference standard. 1 unit.

Purity and quantity is $250 per sample (1 unit) and raw powder purity is $200 for 50 mg, with results in 3 to 5 business days. Send the material sealed and labeled, with the label claim and the form it contains.
No. The $250 test covers identity, purity and quantity by HPLC-UV for purity and assay, with LC-MS to confirm identity. Full testing to the USP Cisatracurium Besylate monograph is available and quoted.
Atracurium is a mixture of ten stereoisomers, and cisatracurium is a single one of them, the 1R-cis,1'R-cis isomer. Other atracurium isomers show up as related compounds in the HPLC purity test.
No. It breaks down by Hofmann elimination and ester hydrolysis, forming laudanosine and other products, and this speeds up with heat and higher pH. Samples should ship cold.
LC-MS detects the doubly charged cisatracurium cation, not the besylate (benzenesulfonate) counter-ions, so identity is confirmed on the cation.
