Physical & Chemical Properties

Appearance: Off-white to white crystalline powder or solid, odorless; hygroscopic and moisture-sensitive, unstable when exposed to light and heat; highly toxic (GHS 06, 08), harmful if swallowed, in contact with skin or inhaled; TSCA listed; WGK Germany: 3; Hazard Class: 6.1.

Density: 1.214 g/cm3 (predicted); LogP: Undetermined; PSA: 104.83; pKa: 9.66±0.43 (predicted); Optical Rotation: -50.0~-55.0 deg (c=1, methanol); RTECS No.: ED7771666.

Melting Point: 122-124℃ (lit.), stable at low temperature, decomposes at high temperature.

Boiling Point: Undetermined, decomposes before boiling at atmospheric pressure.

Solubility: Soluble in DMSO (100 mg/mL), chloroform, methanol; slightly soluble in ethanol (2 mg/mL, with sonication); slightly soluble in water (76 mg/L at 20℃); insoluble in non-polar organic solvents.

Flash Point: Not applicable (combustible solid, Storage Class 11); Vapor Pressure: Negligible at 25℃; forms sterile lyophilized powder when formulated for pharmaceutical use.

Purity: ≥98.0% (analytical grade, HPLC/LC-MS); ≥99.0% (pharmaceutical grade); low impurity content, conforming to pharmaceutical API standards.

Storage Condition: Sealed, desiccated, stored at -20℃, protected from light and moisture; avoid exposure to heat and oxidizing agents; solutions in DMSO can be stored at -20℃ for a short period; shelf life 2 years when stored properly; handle with appropriate protective equipment.

Main Uses

Pharmaceutical: Core API of antineoplastic drugs, sold under the brand name Velcade®; clinically used for the treatment of multiple myeloma (can be combined with melphalan and prednisone for untreated patients, or used alone for relapsed patients) and relapsed/refractory mantle cell lymphoma; acts as a highly selective reversible inhibitor of 26S proteasome, inhibiting cancer cell proliferation and promoting apoptosis.
Medical Research: Used as a research reagent to study the mechanism of proteasome-mediated protein degradation, cell cycle regulation, and the pathogenesis of tumors; widely used in in vitro cell culture and in vivo animal experiments to explore anti-tumor drug combinations and drug resistance mechanisms.
Pharmaceutical Intermediate: Used in the synthesis of bortezomib derivatives and related anti-tumor drugs; also used as a reference substance for drug quality control and analytical detection.
Biochemical Experiment: Used as a biochemical reagent to study the role of proteasome in cellular signaling pathways, such as NF-κB pathway regulation, and to explore the mechanism of cell apoptosis and endoplasmic reticulum stress response.
