Structurally, 538-28-3 QJ9N8049ND S-Benzylthiuronium chloride S-Benzylthiouronium chloride Carbamidothioic acid, phenylmethyl ester, monohydrochloride Pseudourea, 2-benzyl-2-thio-, monohydrochloride Carbamimidothioic acid, phenylmethyl ester, hydrochloride (1:1) Carbamimidothioic acid, phenylmethyl ester, monohydrochloride A-287 X 182 AI3-17804 Benzyl thiopseudourea hydrochloride Benzylisothiourea hydrochloride S-Benzylisothiourea hydrochloride Benzylisothiouronium chloride 2-Benzylisothiouronium chloride Benzylisothiuronium chloride S-Benzylthioformamidine hydrochloride S-Benzylthiopseudourea hydrochloride Benzylthiuronium chloride BTKH EINECS 208-688-6 Isothiouronium chloride, benzyl- NSC 179799 Pseudourea, 2-benzyl-2-thio-, hydrochloride Pseudourea, 2-thio-2-benzyl-, hydrochloride TL 944 USAF EK-2124 UNII-QJ9N8049ND (C8H16N2SHCl) contains sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 208.75 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
