99% HPLC Indole-3-Carbinol (I3C) Powder CAS 700-06-1 | Chinese Manufacturer 

What Is Indole-3-Carbinol? 

Indole-3-Carbinol (I3C, CAS 700-06-1) is a bioactive natural phytochemical naturally formed when cruciferous vegetables like broccoli, cabbage, kale and Brussels sprouts are chopped or chewed. Widely researched and adopted by global supplement manufacturers, I3C delivers proven benefits to support balanced estrogen metabolism and robust cellular antioxidant defense, making it one of the most in-demand functional active ingredients for women’s health nutraceuticals and antioxidant dietary supplements.

While I3C naturally occurs in fresh greens, vegetable-based extraction fails to satisfy large-scale bulk industrial production due to low yield, unstable purity and inconsistent batch quality. Our factory specializes in supplying chemically synthesized Indole-3-Carbinol powder guaranteed with ≥99.0% HPLC purity. This synthetic I3C holds an identical molecular structure and full equivalent biological activity to plant-origin I3C, and has become the standardized mainstream bulk raw material for women’s wellness supplements, antioxidant formulations and pharmaceutical intermediates worldwide.

Key Applications

Nutraceuticals & Dietary Supplements: Supports estrogen balance, breast and cervical health, and antioxidant protection.•• Pharmaceuticals: Investigated for adjuvant use in hormone-related and cellular-protection therapies.•• Cosmeceuticals: Formulated into anti-aging and skin-protective products for free-radical scavenging.

We maintain permanent raw material inventory to avoid stock shortages, delivering stable lead times for global supplement brands, pharmaceutical labs and ingredient distributors.

2.Strict Quality Control, Guaranteed ≥99.0% HPLC Purity

We equip full HPLC, GC and atomic absorption testing labs to run full-item inspection for every batch of synthetic I3C powder, fully complying with your product specification standards:

Stable HPLC purity ≥99.0%, far exceeding low-purity broccoli-extracted I3C (30%-70% purity)

Rigorous control over heavy metals ≤10ppm, zero benzene & toluene solvent residue

Unified batch indicators including melting point, loss on drying and 80-mesh particle size Every shipment comes with official COA test reports, meeting FDA, GMP and global nutraceutical safety requirements for women’s health supplement formulations.

3.Cost-Effective Synthetic Process vs Plant Extraction

Our chemical synthesis route eliminates massive costs from vegetable raw materials, complex plant purification and low extraction yield. Without reliance on broccoli, cabbage and other cruciferous crop pricing volatility, we offer competitive long-term bulk pricing. Clients can cut overall ingredient costs while receiving standardized high-purity I3C with identical molecular structure and bioactivity to naturally-occurring vegetable I3C.
