Local anesthetic (amino amide)
Identity: Ropivacaine hydrochloride
IUPAC name: (2S)-N-(2,6-dimethylphenyl)-1-propylpiperidine-2-carboxamide;hydrochloride
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 a chloride test, assay by titration, organic impurities by HPLC, and color, clarity, pH and water, plus sterility and bacterial endotoxins for sterile grades. Full testing to the USP Ropivacaine Hydrochloride 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 Ropivacaine Hydrochloride monograph is available and quoted.
Ropivacaine is the single S enantiomer, and the R enantiomer is a specified impurity. The USP monograph includes an enantiomeric purity test; the $250 HPLC test does not separate enantiomers, so chiral testing is quoted separately.
It is usually supplied as the monohydrate, which weighs about 6% more than the anhydrous salt, so results are reported against the labeled form.
