Highly selective developer for high-resolution imaging of iodine-based latent prints on porous and semi-porous surfaces.
Non-corrosive formulation ensures substrate integrity—safe for paper, cardboard, currency, and archival documents.
Rapid visual development (typically within 30–90 seconds) without requiring heat or fuming chambers.
Stable aqueous solution with extended shelf life (>24 months unopened at room temperature).
Low odor and low volatility—designed for routine lab and field use with minimal ventilation requirements.
Forensic latent fingerprint development on banknotes, passports, and identity documents.
Crime scene investigation on paper-based evidence including envelopes, letters, and packaging materials.
Quality assurance in anti-counterfeiting document inspection workflows.
Academic and training labs for forensic science education and methodology validation.
Post-nitric acid or cyanoacrylate fuming enhancement to improve contrast and ridge detail clarity.
| Chemical Type | Iodine complex in buffered aqueous solution |
| Product Form | Liquid concentrate (ready-to-use after dilution with deionized water) |
| Appearance | Clear, amber-brown solution |
| pH (1% aqueous solution) | 6.8–7.2 |
| Primary Applications | Latent fingerprint development on porous substrates |
| Key Features | Reversible reaction, non-destructive, compatible with subsequent DNA recovery |
| Benefits | Enables sequential processing (e.g., iodine → cyanoacrylate → dye staining) |
| Regulatory Compliance | REACH compliant; no SVHCs above threshold; not classified as hazardous under GHS (Cat. 0) |
| Common Compatible Systems | Suitability |
| Cyanoacrylate (CA) fuming chambers | Highly Recommended – Ideal for post-CA enhancement of weak ridge detail |
| Ninhydrin-treated paper | Recommended – Apply before ninhydrin for complementary visualization; avoid overlapping sequences |
| DFO (1,8-Diazafluoren-9-one) reagents | Suitable – Can be used prior to DFO; requires full drying and fixation between steps |
| Photographic documentation systems (e.g., ALS, RUVIS) | Highly Recommended – Strong fluorescence quenching enables high-contrast visible imaging |
Q1: What is the CAS Registry Number for IC Developer?
A: IC Developer is a proprietary multi-component formulation; individual active ingredients include iodine (CAS 7553-56-2) and potassium iodide (CAS 7681-11-0), but the final mixture does not carry a single CAS number per IUPAC guidelines.
Q2: What is the recommended working concentration and application method?
A: Dilute 1 part IC Developer concentrate with 4 parts deionized water. Apply via gentle brush, spray, or dip immersion; air-dry flat for optimal results. Avoid oversaturation to prevent background staining.
Q3: How does IC Developer compare to traditional iodine fuming?
A: Unlike volatile iodine vapor, IC Developer delivers controlled, localized iodine exposure via liquid phase—improving reproducibility, reducing operator exposure, and eliminating need for sealed fuming cabinets.
Q4: Is IC Developer compatible with downstream DNA analysis?
A: Yes—studies confirm no significant inhibition of STR profiling when standard collection protocols (e.g., tape-lift or swabbing after full drying) are followed. Residual iodine does not interfere with extraction or amplification.
Q5: Does IC Developer cause migration or smearing of latent prints during application?
A: No—when applied correctly (light saturation, no pooling), IC Developer exhibits minimal lateral diffusion. Excess moisture is the primary cause of ridge distortion; always use lint-free applicators and monitor substrate absorption rate.
