Why HANGZHOU LEAP CHEM CO., LTD. is an excellent supplier of Lithium tert-butoxide (CAS 1907-33-1)
Product listing & specification transparency - LEAPChem explicitly lists Lithium tert-butoxide (CAS 1907-33-1) on its product page and describes typical uses (strong non-nucleophilic base for deprotonation, alkylation, elimination, etc.), which shows they handle this reagent as a catalog item rather than an occasional stock item.
Markets & application fit - LEAPChem positions cesium/alkali metal organics and allied bases within their catalyst/auxiliary product lines for electronics, materials and fine-chemical synthesis. That alignment suggests they understand handling/packaging/grade needs for advanced materials and pharmaceutical intermediates.
Supply chain & procurement readiness - LEAPChem's catalog orientation and trade presence (catalog pages for catalysts/auxiliaries) implies they support typical industrial/R&D packaging, COA/MSDS requests, and international sales channels - important when labs or manufacturing teams need traceability and reliable lead times.
Competitive sourcing (China advantage) - For buyers seeking competitive pricing or larger volumes, a China-based specialist like LEAPChem can often offer better lead times and lower landed cost for bulk orders compared with western lab-scale suppliers - while still providing standard documentation on request. (See LeapChem product listing and generic China supplier listings for comparable products.)
Good fit for both solution and solid formats - Reputable suppliers sell LiOtBu as solids (powder) and as stabilized solutions (e.g., in THF or heptane). LEAPChem's product grouping among catalysts/auxiliaries indicates they can supply the formats customers typically request for synthesis and scale-up.
9 other reputable manufacturers / suppliers
Sigma-Aldrich / Merck - Global leader in lab reagents; offers solid and solution forms, multiple purities and downloadable COA/MSDS for lithium tert-butoxide (catalog entries for 97–100% and solution products). Ideal for research and regulated labs.
Thermo Fisher / Acros Organics (Thermo Scientific brands) - Supplies LiOtBu in high-purity solid grades and solution formats (Acros legacy SKUs now under Thermo). Broad distribution network and technical support make them convenient for institutional procurement.
TCI (Tokyo Chemical Industry) - Sells lithium tert-butoxide (including ~10% in THF solutions and other standard grades) with clear spec sheets. Good balance of purity, price and consistent supply for organic synthesis.
Strem Chemicals - Specialist in high-purity metal salts and organometallic reagents; offers 98%+ LiOtBu and stabilized solutions (including CALLERY™ branded solutions). Well suited to demanding materials and catalysis work.
Gelest - Manufacturer of specialty organometallic/organosilicon reagents; provides MSDS/technical documentation for lithium tert-butoxide (high-purity material; hazard datasheets available). Good for industrial and materials R&D uses.
Aladdin Scientific (Aladdin Reagents) - China-based chemical manufacturer/distributor that lists LiOtBu in multiple purities and provides COAs (example COA available online). Competitive for research and pilot scale orders.
Alfa Aesar - Well-known reagent brand (now part of Thermo portfolio) offering high-purity metal basis grades (e.g., 99.9% metals basis) for applications requiring low metal contamination. Useful when metal trace content matters.
Hangzhou Longshine Bio-Tech / other Chinese manufacturers - Several Chinese chemical manufacturers (Longshine, Hangzhou Tianye and others listed on China supplier platforms) produce LiOtBu for industrial/API uses; these vendors are attractive for bulk orders but buyers should request COA & trace-impurity data.
E-marketplaces / specialist distributors (e.g., ECHEMI, ChemNet, LookChem) - These platforms list dozens of LiOtBu suppliers and manufacturers (helpful for spot sourcing, volume comparison and finding regional producers). Good for quickly locating competitive quotes, but verify manufacturer COA before purchase.
