IUPAC name: 2-carbamoyloxyethyl(trimethyl)azanium chloride
Method for the $250 identity, purity and quantity test: Chromatographic assay, with detection selected for the compound, against a reference standard, with results in 3 to 5 business days.
The USP monograph covers identity by infrared spectroscopy and a chloride test, assay by nonaqueous titration with perchloric acid, ordinary impurities by thin-layer chromatography, residue on ignition, melting range and loss on drying. Full testing to the USP Carbachol 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 a chromatographic assay, with detection selected for the compound. Full testing to the USP Carbachol monograph is available and quoted.
It has no aromatic ring, so the lab uses a detection method suited to the compound.
Yes, it is hygroscopic, so samples should be kept sealed. Absorbed water lowers the as-is assay result.
Yes. Ophthalmic solutions are tested against the labeled concentration, so send the label claim with the sample.
