Enhanced description: This product is a research-grade crystalline indole-3-acetic acid intended for plant physiology, tissue culture, and molecular biology applications. Manufacturer: MOLEQULE-ON, New Zealand. Supplier: EMDA. The material is supplied in a 10 g size (powder) and is suitable for preparing sterile stock solutions for media formulation and experimental assays.

• Key specifications: molecular formula C10H9NO2, molecular weight ~175.18–175.19 g·mol⁻¹, off-white to tan crystalline powder. (fishersci.com)
• Purity & physical: commonly offered at ≥98% purity for research use; melting point ~165–169 °C (literature). (mpbio.com)
• Solubility & handling: sparingly soluble in water; soluble in DMSO, ethanol, or dilute alkaline (NaOH/KOH) solutions — prepare concentrated stocks in DMSO or dilute base, filter-sterilize (0.22 µm) and add to cooled media. Protect from light and store cold (typically ≤-20 °C for long term or 4 °C short term). (chemicalbook.com)

Features & common uses:

• Used as the principal natural auxin to promote cell elongation, root induction, callus formation, and to study auxin signaling in plant biology. (britannica.com)
• Widely used in plant tissue culture and media formulations at low (micromolar) working concentrations for organogenesis and rooting; optimal dose is species- and application-dependent and should be titrated experimentally. (plant.rtc.riken.jp)
• Employed as a research reagent in auxin-inducible degron (AID) systems and related molecular biology tools where auxin or analogs trigger targeted protein degradation. (tocris.com)

Short handling notes: prepare stocks in amber vials, minimize light/air exposure, avoid autoclaving stock solutions (use sterile filtration), and consult the supplier's Certificate of Analysis and Safety Data Sheet for lot-specific purity and hazard information prior to use. (tissueculture.org)
